Heard somewhere that to get the holy black type boom some were using the likes of H4198 and RL7 in their 45 LC gen 1 SAA's. I don't care if my boom factor is low but I do care if it's to high. 5.5" barrel. Thoughts

went with 18 of alliant 2400. worried about S.E.E.
Thanks for all the replies. Makes me glad for the help I've given here in years past. Apparently "What goes round comes round" is true. This place sure ain't no where near what it was
powders too slow burning, may cause a burst cylinder. Blackhorn 209 is a wonderful powder in the 45. 22 grains and a cci 350 will be as fast as original black powder loads.
SEE is not the problem with that load, but over pressure POSSIBLY is for a 1st generation. Go with the Black Powder or its substitute as suggested. Anything over 15K cup is suspect in weakening the metal somehow, someway. 25 grains of RL7 is fine for a Ruger type, producing 30K max. ... felix
new colt cylinder and barrel should up the pressure limit somewhat
What is s.e.e.?
A slow rifle powder in a sixgun can do this. The primer goes igniting some of the powder charge, the bullet moves forward into the throat and stops, the rest of the charge ignites and blows to top off the gun. Happened to a friend of mine in a 500 maximum with Reloader 7.
well it's all new colt 2nd gen stuff, but I'm going to try 18 grs of alliant 2400
While I don't believe it would be hazardous, you are going to get lots if unburned powder which can jam a revolver mechanism. It does in my 20" lever gun.
18 grains of 2400/255 bullet seems quite a charge for your Colt. Would not do it with mine nor would I go with the rifle powders either.. Have patience if you want a thoughtful answer.
Ya I even reduced that to 16. The nice thing with cast as opposed to copper clad is less initial pressure spike. 16 grains of 2400 under the 255 is kinda considered the baby sitters loadQuote:

In my .45 SAA's I use 15 gr of 2400, shoot 3rd gens. Then again I've been shooting much more Unique than 2400 in my SAA .45's.
